以下示例将在将HTML字符串解析为Document对象后展示DOM方法的使用.
Document document = Jsoup.parse(html);
Element sampleDiv = document.getElementById("sampleDiv");
Elements links = sampleDiv.getElementsByTag("a");其中
document : document对象代表HTML DOM.
Jsoup : 用于解析给定HTML字符串的主类.
html : HTML字符串.
sampleDiv : Element对象表示由id"sampleDiv"标识的html节点元素.
links : Elements对象表示由标签"a"标识的多个节点元素.
parse(String html)方法将输入HTML解析为新的Document.此文档对象可用于遍历和获取html dom的详细信息.
使用您选择的任何编辑器创建以下Java程序比方说C:/> jsoup.
JsoupTester.java
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
public class JsoupTester {
public static void main(String[] args) {
String html = "<html><head><title>Sample Title</title></head>"
+ "<body>"
+ "<p>Sample Content</p>"
+ "<div id='sampleDiv'><a href='www.google.com'>Google</a></div>"
+"</body></html>";
Document document = Jsoup.parse(html);
System.out.println(document.title());
Elements paragraphs = document.getElementsByTag("p");
for (Element paragraph : paragraphs) {
System.out.println(paragraph.text());
}
Element sampleDiv = document.getElementById("sampleDiv");
System.out.println("Data: " + sampleDiv.text());
Elements links = sampleDiv.getElementsByTag("a");
for (Element link : links) {
System.out.println("Href: " + link.attr("href"));
System.out.println("Text: " + link.text());
}
}
}编译班级使用 javac 编译器如下:
C:\jsoup>javac JsoupTester.java
现在运行JsoupTester来查看结果.
C:\jsoup>java JsoupTester
查看结果.
